Octodefense

Earth’s defense

Octodefense is a sci-fi tower defense strategy game for PC about humanity fighting an enormous entity that emerges through a rift in the sky. You command the covert Cosmic Hostile Operations & Threat Organization, or C.H.O.T.O., and build defenses along the entity’s armored tentacles as they reach toward Earth. Your orders are to protect ground points and cut off the creature’s hold on the planet.

Turrets and shifting lanes

The battlefields run along the entity’s tentacles, which can move, split, and change the routes enemies take. You’ll need to adjust firing arcs and choke points as the lanes shift. Build, reposition, and upgrade weapons including kinetic railguns, plasma cannons, cryo-inhibitors that slow enemy swarms, and energy beam towers.
